Description

Technical Field

[0001] The present invention relates to a method for replacing a control panel that controls a plurality of components provided in an elevator, and a base mount used for the replacement work of the control panel.

Background Art

[0002] Conventionally, when renewing the facilities of an elevator installed in a multi-story building or the like, the hoistway in which the elevator is installed is reused, and all components constituting the elevator are often replaced. Specifically, the elevator car, the drive mechanism for raising and lowering the car, etc. are replaced. Also, conventionally, in order to reduce the cost of renewal, for example, only the car, only the hoisting machine in the drive mechanism, etc., only some components may be replaced.

[0003] Due to recent technological improvements, a control panel (new control panel) that controls an elevator using new technology has functions and performance that are much superior to those of existing control panels. For this reason, when renewing an elevator, there are many demands to replace the old control panel with a new one. In the conventional replacement work of the control panel, various cables connecting each component such as the drive mechanism and the control panel were also replaced.

[0004] As a related technology, specifically, conventionally, a guide sleeve extending into the hoistway from an existing wiring opening was cut at the introduction part on the hoistway side, and new various wirings were laid in the hoistway through a wiring opening in which a new protective sleeve was installed in place of the guide sleeve remaining after cutting, so that various wirings could be passed from the control panel to the hoistway without performing special drilling work (see, for example, Patent Document 1 below).

Embodiments for Carrying Out the Invention

[0021] Hereinafter, with reference to the accompanying drawings, a method for replacing a control panel and a preferred embodiment of a base mount according to the present invention will be described in detail. A preferred embodiment of the base mount will be described in detail.

[0022] (Example of Elevator Configuration) First, the configuration of the elevator that is the object of the replacement work method of the embodiment according to the present invention will be described. FIG. 1 is an explanatory diagram showing an example of the configuration of an elevator. In FIG. 1, the elevator 100 that is the object of the replacement work method of the embodiment according to the present invention is installed, for example, in a building such as a multi-story building, and consists of only one hoistway, and only one unit is provided in the building and operates independently. The elevator 100 is, for example

[0023] In FIG. 1, the elevator 100 that is the object of the replacement work method of the embodiment according to the present invention 100 is installed, for example, in a building such as a multi-story building, and consists of only one hoistway, and only one unit is provided in the building and operates independently. The elevator 100 is, for example and is installed in a building such as a multi-story building, and consists of only one hoistway, and only one unit is provided in the building and operates independently. The elevator 100 is, for example It can be realized by a rope type (traction type) elevator.

[0024] The elevator 100 is provided with a cage (riding cage) 101 for carrying people and goods. The cage 101 is provided one for each hoistway. The hoistway penetrates each floor in the building in the vertical direction, that is, along the moving direction of the cage 101. In the present embodiment, The elevator 100 operating alone is composed of a control panel 106 described later and components controlled by the control panel 106. The elevator 100 operating alone does not include components outside the building such as a monitoring center installed at a remote location of the elevator 100.

[0025] The hoistway is provided on the side with a guide rail (not shown) for guiding the ascending and descending position of the cage 101. Further, the hoistway is provided at the bottom with a buffer 102 for cushioning the impact when the cage 101 accidentally falls and collides with the bottom surface. The buffer 102 may be a spring type buffer 102 that uses the elastic force of a spring to cushion the impact, or an oil-filled buffer 102 that uses hydraulic resistance to cushion the impact. The buffer 102 may also be provided on the ceiling surface of the hoistway.

[0026] The cage 101 is connected to one end of a rope 103. The rope 103 is hung on a pulley type pulley (not shown) and a hoisting machine (traction machine) 104, and the other end is connected to a counterweight 105. Specifically, the rope 103 can be realized by, for example, a steel wire.

[0027] The hoisting machine 104 in the rope type elevator 100 is, for example, the elevator 10 It is installed in the machine room provided at the topmost part of 0. The hoist 104 is controlled by, for example, an inverter. It is controlled to stop rotating on the floor where the car 101 stops, and is driven and controlled by the control panel 106. In the rope-type elevator 100, the frictional force (traction) between the rope 103 and the pulley generated by driving the hoist 104 is utilized to raise and lower the car 101. The hoist 104 is driven and controlled by the control panel 106 provided in the elevator 100.

[0028] The hoist 104 is provided with an encoder (not shown), and the control panel 106 can judge the rotation speed and rotation position of the hoist 104 based on the output signal from the encoder. The encoder may use, for example, an absolute encoder or an incremental encoder.

[0029] In addition, the elevator 100 is provided with an electromagnetic brake 107, a speed regulator (governor machine) 108, a limit switch 109, etc. The electromagnetic brake 107 is provided with a coil and is driven and controlled by the control panel 106 to utilize the electromagnetic force generated by energizing the coil to stop the rotation of the hoist 104. The electromagnetic brake 107 can hold the state in which the rotation of the hoist 104 is stopped.

[0030] The electromagnetic brake 107 stops the rotation of the hoist 104 when the power supply is stopped due to a power outage or the like. Specifically, for example, an electromagnetic brake 107 of the non-excitation operation type that operates by the force of a spring to stop the rotation of the hoist 104 when the power supply to the coil is cut off during a power outage or the like can be used. ​​​​​​​​​​​​​​

[0031] The speed governor 108 detects an overspeed of the cage 101. The speed governor 108 is, for example, a centrifugal speed governor equipped with a governor rope 108a, a governor pulley 108b, a rotating weight (not shown), etc. In such a speed governor 108, the governor rope 108a is interlocked with the operation of the cage 101. The governor pulley 108b rotates in conjunction with the operation of the governor rope 108a. The rotating weight operates according to the rotational speed of the governor pulley 108b, that is, the magnitude of the centrifugal force caused by the rotation of the governor pulley 108b. Specifically, the rotating weight operates to open to the outer peripheral side of the governor pulley 108b when the rotational speed of the governor pulley 108b is high, and operates to close to the inner peripheral side of the governor pulley 108b when the rotational speed of the governor pulley 108b is low. The limit switch 109 is provided with a switch lever (not shown) for switching the supply / cut-off of power to the hoist 104. The switch lever is positioned at a position where power is supplied to the hoist 104 during normal times, and is displaced to a position where the supply of power to the hoist 104 is cut off when energized by the rotating weight of the speed governor 108. The rotating weight of the speed governor 108 biases the switch lever so that the switch lever is displaced to a position where the supply of power to the hoist 104 is cut off when the lifting / lowering speed of the cage 101 exceeds a certain speed with respect to the rated speed. Thereby, when an overspeed occurs in the cage 101, the operation of the hoist 104 can be stopped and the cage 101 can be stopped.

[0032]

[0033]

[0034] ​​​​​​​​​​​​​​

[0035] Furthermore, the elevator 100 may be provided with an emergency stop device. The emergency stop device when the operation of the car 101 and the operation of the governor rope 108a are different, that is, when the governor rope 108a has stopped but the car 101 is still operating, forcibly stops the operation of the car 101. Since the emergency stop device can be easily realized by using various known techniques, its description is omitted.

[0036] The car 101 is provided with a door 101a. The car 101 also includes a motor (not shown) for opening and closing the door 101a, a door open / close sensor (not shown) for detecting the open / closed state of the door 101a, and an operation panel 101b, etc. The motor for opening and closing the door 101a is driven and controlled by the control panel 106 to open and close the door 101a.

[0037] The door open / close sensor changes its output according to whether the door 101a or the door 110a is in the open state or the closed state according to the state of the safety shoe located between the door 101a and the door 110a. The door open / close sensor can be realized by, for example, a microswitch or a photoelectric sensor. The door open / close sensor is connected to the control panel 106 via wiring, and the signal output from the door open / close sensor is input to the control panel 106 via the wiring.

[0038] Doors 110a are respectively provided at positions (landing) 110 corresponding to each floor in the hoistway. The doors 110a provided at the landing 110 are locked by a device called an interlock (not shown). The interlock is when the elevator 100 stops at a floor ​​​​​​​​​​​The door 1 of the cage 101 is unlocked by engaging with the opening and closing mechanism of the door 01a only when the motor provided in the cage 101 has arrived at the destination state. As a result, only the door 110a provided at the landing 110 on the floor where the cage 101 is located can be opened and closed in conjunction.

[0039] Each landing 110 is provided with an operation panel 111 having a landing call button 111a, a display 111b for displaying the floor where the cage 101 is located, and the like. The operation panel 1 11 is provided with a control board 111c for the operation panel 111, respectively, and is connected to the control panel 106 via the control board 111c.

[0040] Components such as the hoist 104 controlled by the control panel 106, and components such as sensors that output information regarding the state of each part of the elevator 100 to the control panel 106 are connected to the control panel 106 via a cable (see FIG. 8B). For example, the components provided in the cage 101 are connected to the control panel 106 via a cable called a tail cord or the like routed in the cage 101. Specifically, for example, the door opening and closing sensor of the cage 101, lighting (see reference numeral 203 in FIG. 2), the operation panel 101b, and various sensors for ensuring the safety of users and other components are connected to the control panel 106 via a cable (tail cord).

[0041] Also, specifically, for example, the control board 111c is connected to the control panel 106 via a cable routed through the hoistway from the control board 111c. Also, specifically, for example, various sensors installed in the hoistway and the like are connected to the control panel 106 via a cable.

[0042] The control panel 106 is installed in, for example, the machine room. In this case, one end of the cable is connected to each component provided in the elevator 100, routed from each component to the machine room, and the other end is connected to the control panel 106. The control panel 106 controls a plurality of components provided in the elevator 100. The control panel 106 controls components such as the hoisting machine 104, the electromagnetic brake 107, and the motors for opening and closing the doors 101a and 105a based on the up signals (call signals) output from the control board for the operation panel 101b. Also, the control panel 106 determines whether each component is operating normally based on the up signals output from components such as the hoisting machine 104 (encoder), the brake sensor, and the door open / close sensor. Further, the control panel 106 outputs a down control signal including a floor signal indicating the floor where the car 101 is located to the control board for the operation panel 101b, and causes the operation panel 101b to display the floor where the car 101 is located and the moving direction (ascending or descending). Each part of the control panel 106 is mounted on a single or multiple circuit boards and is housed in an iron box-shaped housing (see FIG. 8A). The control panel 106 controls a plurality of components provided in the elevator 100.

[0043] The control panel 106 controls components such as the hoisting machine 104, the electromagnetic brake 107, and the motors for opening and closing the doors 101a and 105a based on the up signals (call signals) output from the control board for the operation panel 101b.

The elevator 100 may not be provided with the display 111b. The elevator 100 may not be provided with the display 111b.

[0051] Similar to the control board for the operation panel 101b, the control board 111c generates a call signal corresponding to the input operation each time it receives an input operation on the landing call button 111a by a user or the like of the elevator 100, and outputs the generated call signal to the control panel 106. user or the like of the elevator 100, and outputs the generated call signal to the control panel 106. The elevator 100 may not be provided with the display 111b.

[0052] In this embodiment, among the respective parts provided in the elevator 100, for example, the parts that output a signal to the control panel 106, so-called "up signal", can realize the constituent parts according to this invention. Also, in this embodiment, the elevator 10 panel 106, so-called "up signal", can realize the constituent parts according to this invention. Also, in this embodiment, the elevator 10 0 can realize the constituent parts according to this invention. Also, in this embodiment, the elevator 10 ​Among the respective parts provided by 0, for example, according to a signal output from the CPU (Central Processing Unit) of the control panel 106, that is, a so-called "downlink signal", each part that operates can realize the component according to this invention.

[0053] Specifically, the component can be realized by, for example, the drive mechanism of the elevator 100. More specifically, the drive mechanism of the elevator 100 can be realized by, for example, the hoisting machine 104, the electromagnetic brake 107, a motor for opening and closing the door 101a, and the like. Such a drive mechanism of the elevator 100 operates according to the downlink signal output from the control panel 106. In addition, the drive mechanism of the elevator 100 may further output an uplink signal to the control panel 106.

[0054] In addition, the component can be realized by, for example, the control mechanism of the landing 110 of the elevator 100. Specifically, the control mechanism of the landing 110 of the elevator 100 can be realized by, for example, the operation panel 111 (control board 111c) provided at each landing 110. In addition, the component can be realized by the control mechanism of the car 101 of the elevator 100. Specifically, the control mechanism of the car 101 of the elevator 100 can be realized by, for example, the operation panel 101b provided on the car 101.

[0055] In addition, the component can be realized by, for example, the sensor mechanism of the elevator 100. Specifically, the sensor mechanism of the elevator 100 can be realized by, for example, various sensors such as the limit switch 109 and the door open / close sensor. ​​​​​​​​​​S outputs an upward signal to the control panel 106.

[0056] In this embodiment, a replacement method for replacing the control panel (old control panel ) 106 with a new control panel will be described. The new control panel has the same configuration as the old control panel 10 6 and is provided with an iron housing in a box shape that houses each part constituting the new control panel (see Fig. 8D).

[0057] (An example of the configuration of the new control panel) Next, the configuration of the new control panel will be described. Fig. 4 is an explanatory drawing showing an example of the configuration of the new control panel. As shown in Fig. 4, the new control panel 400 includes a CPU 401, a memory 402, an input terminal 403, an output terminal 404, and a communication I / F (Interface) 405 (all are not shown). Each part 401 - 405 included in the new control panel 400 is connected by a bus 406 respectively.

[0058] The CPU 401 of the new control panel 400 controls a plurality of components included in the elevator 100 and is in charge of the overall control of the elevator 100. The memory 402 of the new control panel 400 stores programs, data, etc. used for controlling a plurality of components included in the elevator 100. The CPU 401 performs arithmetic processing using programs, data, etc. stored in the memory 402 based on, for example, an upward signal input via the input terminal 403. Also, the CPU 401 outputs a signal based on the result of the arithmetic processing to the corresponding component via the output terminal 404, for example.

[0059] Specifically, the CPU 401, for example, performs arithmetic processing using programs and data stored in the memory 402 based on an upward signal output from the control board for the operation panel 101b. ​Based on the up signal (call signal), a down signal for control of each component such as the hoist 104, the electromagnetic brake 107, and the motor for opening and closing the door 101a, 110a is generated, and the generated down signal for control is output to each corresponding component.

[0060] Also, the CPU 401 determines, for example, whether each component is operating normally based on the up signals output from each component such as the hoist 104 (encoder), the brake sensor, and the door opening / closing sensor. Further, the CPU of the new control panel 400 outputs a down signal for control including a floor signal indicating the floor where the cage 101 is located to the control board for the operation panel 101b, and causes the operation panel 101b to display the floor where the cage 101 is located and the moving direction (ascending or descending).

[0061] The input terminal 403 of the new control panel 400 is a hardware interface that connects a plurality of components provided in the elevator 100 and the CPU of the control panel 106, receives the input of signals output from each component, and outputs the received signal to the CPU of the new control panel 400. The input terminal 403 receives, for example, the input of the up signal output from each component of the elevator 100 to the new control panel 400.

[0062] Specifically, the input terminal 403 receives, for example, the input of the call signal output from the control board for the operation panel 101b or the control board for the operation panel 101b. Also, the input terminal 403 of the new control panel 400 receives, for example, the input of the signal output from the encoder. Further, the input terminal 403 receives, for example, the input of signals from the limit switch 109, the door opening / closing sensor, the electromagnetic brake 1 ​​​​​​​​​Signals output from various sensors such as brake sensors whose output changes depending on the operation of 07 The brake sensor can be, for example, a micro switch or a photoelectric sensor. This can be achieved by:

[0063] The output terminal 404 of the new control panel 400 is connected to a plurality of components of the elevator 100 and the new control A hardware interface that connects the CPU 401 of the control board 400. The downstream signal output from the CPU 401 of the board 400 is output to the corresponding component. The output terminal 404 receives, for example, the control signal generated by the CPU 401 of the new control board 400. The down signal for the elevator is a hoist 104, an electromagnetic brake 107, a door 101a of the cage 101, and a platform 1 The signal is output to a motor or the like that opens and closes the door 110a of the sensor 10.

[0064] The communication I / F 405 communicates with the management server computer via a network such as the Internet. The communication I / F 405 is connected to a computer (not shown). For example, mobile phone lines (such as LTE (Long Term Evolution ), PHS (Personal Handy-phone System) and other wireless communication The communication I / F 405 can be realized by the communication interface. The F405 can be used with a wired communication interface such as a modem or LAN adapter. The above-mentioned embodiment may be realized by the above-mentioned method.

[0065] The management server computer is a computer that is connected to the elevator 100 to be monitored. The elevator 100 is installed in a remote location different from the elevator 100. It is. The management server computer can be installed, for example, in a maintenance management company or the like responsible for the maintenance management of the elevator 100. It can be installed in a maintenance management company or the like.

[0066] The communication I / F 405 transmits the signal for reporting issued from the CPU 401 to the management server computer. The signal for reporting is output from the CPU 401 via the communication I / F 405, for example, when a failure in the elevator 100 is detected or when the operation mode of the elevator 100 changes. When a failure in the elevator 100 is detected or when the operation mode of the elevator 100 changes, etc., it is output to the management server computer via the communication I / F 405. When a failure in the elevator 100 is detected or when the operation mode of the elevator 100 changes, etc., it is output from the CPU 401 to the management server computer via the communication I / F 405. It is output to the management server computer via the communication I / F 405.

[0067] In addition, the communication I / F 405 receives various instructions such as the execution instruction of the diagnostic operation transmitted from the management server computer and outputs them to the CPU 401. The diagnostic operation is to output signals for operating each part of the elevator 100 provided in the new control panel 400 in a predetermined order, and to output signals from the new control panel 400 indicating whether each part operates normally according to the output signals. The management server computer outputs an execution instruction of the diagnostic operation, for example, periodically (for example, every time the end of the month arrives). It receives various instructions such as the execution instruction of the diagnostic operation transmitted from the management server computer and outputs them to the CPU 401. The diagnostic operation is realized by outputting signals for operating each part of the elevator 100 provided in the new control panel 400 in a predetermined order and outputting signals from the new control panel 400 indicating whether each part operates normally according to the output signals. The management server computer outputs an execution instruction of the diagnostic operation, for example, periodically (for example, every time the end of the month arrives). For each part of the elevator 100 provided in the new control panel 400, signals for operating the parts in a predetermined order are output, and signals indicating whether each part operates normally according to the output signals are output from the new control panel 400. It is realized by outputting signals for operating each part of the elevator 100 provided in the new control panel 400 in a predetermined order and outputting signals from the new control panel 400 indicating whether each part operates normally according to the output signals. The management server computer outputs an execution instruction of the diagnostic operation, for example, periodically (for example, every time the end of the month arrives). For example, it outputs an execution instruction of the diagnostic operation periodically (for example, every time the end of the month arrives).

[0068] The new control panel 400 and the management server computer are connected via the communication I / F 405 via the Internet instead of a public voice network such as a telephone line, so that the situation of the elevator 100 can be grasped in a timely manner when an emergency occurs such as an earthquake, avoiding delays in grasping the situation of the elevator 100 due to a breakdown of the telephone line. By connecting the new control panel 400 and the management server computer via the communication I / F 405 via the Internet instead of a public voice network such as a telephone line, it is possible to avoid delays in grasping the situation of the elevator 100 when an emergency occurs such as an earthquake, so that when an emergency occurs such as an earthquake, the situation of the elevator 100 can be grasped in a timely manner, avoiding delays in grasping the situation of the elevator 100 due to a breakdown of the telephone line. This can avoid delays in grasping the situation of the elevator 100 due to a breakdown of the telephone line when an emergency occurs such as an earthquake. In this way, in the situation where the elevator 100 is remotely monitored using the management server computer, prompt response can be taken when a malfunction occurs in the operation of the elevator 100.

[0069] The new control panel 400 may further be connected to the public voice network via the communication I / F 405. The public voice network includes a fixed telephone network (public switched telephone network) and a mobile telephone network. The public voice network is composed of a plurality of switches, such as a subscriber line switch that houses telephone lines, a relay switch that bundles subscriber line switches, and a gateway switch that connects to the telephone networks of other operators, which are not shown in the figure. Since the public voice network is a well-known technology, its description is omitted. By connecting the new control panel 400 to the public voice network via the communication I / F 405, voice communication between the intercom terminal device 205 and the management center can be realized. In this case, the new control panel 400 may perform data communication using an LTE board (LTE module). That is, the LTE board may be used for both data communication and voice communication. By performing communication using LTE, the quality of communication can be ensured. Also, since the installation location of the elevator 100 is fixed, by performing communication using LTE, the installation position of the elevator 100 can be grasped.

[0070] Note that in this case, the new control panel 400 may perform data communication using an LTE board (LTE module). That is, the LTE board may be used for both data communication and voice communication. By performing communication using LTE, the quality of communication can be ensured. Also, since the installation location of the elevator 100 is fixed, by performing communication using LTE, the installation position of the elevator 100 can be grasped. Note that in this case, the new control panel 400 may perform data communication using an LTE board (LTE module). That is, the LTE board may be used for both data communication and voice communication. By performing communication using LTE, the quality of communication can be ensured. Also, since the installation location of the elevator 100 is fixed, by performing communication using LTE, the installation position of the elevator 100 can be grasped.

[0071] Each part 401 - 405 included in the new control panel 400 is mounted on a single or multiple boards and is housed in an iron housing in a box shape (see Fig. 8D). Each part 401 - 405 included in the new control panel 400 may be in the form of a PLC (Programmable Logic Controller). The housing further includes relays, inverters, circuit breakers, fuses, transformers, electromagnetic switches, timers, counters, etc. for the elevator. Each part 401 - 405 included in the new control panel 400 is mounted on a single or multiple boards and is housed in an iron housing in a box shape (see Fig. 8D). Each part 401 - 405 included in the new control panel 400 may be in the form of a PLC (Programmable Logic Controller). The housing further includes relays, inverters, circuit breakers, fuses, transformers, electromagnetic switches, timers, counters, etc. for the elevator. circuit breakers, fuses, transformers, electromagnetic switches, timers, counters, etc. for the elevator. Each part related to the control is accommodated. The lower side of the housing of the new control panel 400 is an opening (the lower surface opening of the new control panel 4 00) for routing the cables connected to the components provided in the elevator 100 into the housing. 00 is provided.

[0072] The new control panel 400 receives the input of signals to the new control panel 400 and outputs signals based on the input signals. The new control panel 400 operates according to a program different from the program used by the control panel 106. The new control panel 400 understands machine language (machine code), that is, an electrical signal that can be represented by two values of "0" and "1", which is a signal different from the signal that the control panel 106 can understand. Moreover, the new control panel 400 outputs signals with the same meaning as the signals output by the old control panel 106 to a plurality of components controlled by the control panel 106, but which are signals different from the signals that the components can understand. Specifically, the new control panel 400 outputs, for example, signals based on a control program described in a type of programming language different from the type of programming language in which the control program related to the control by the old control panel 106 is described. Or, specifically, the new control panel 400 may output signals based on a control program described in the same type of programming language as the type of programming language in which the control program related to the control by the old control panel 106 is described, but which is described in a description method different from the description method of the control program related to the control by the old control panel 106. That is also possible.

[0073]

[0074] That is also possible.

[0075] Note that the new control panel 400 outputs signals that can be understood by the plurality of components controlled by the old control panel 106, similarly to the signals output by the old control panel 106. That is, the new control panel 400 may output signals based on a control program described in the same type of programming language and in the same description format as the control program for the control by the old control panel 106.

[0076] The control program for the control by the new control panel 400 has advanced in performance for performing advanced control and is often more complex than the control program for the control by the old control panel 106. For this reason, among the plurality of components provided in the elevator 100, there are cases where they can understand the signals output by the old control panel 106 but cannot understand the signals output by the new control panel 400.

[0077] Due to such circumstances, in the conventional replacement work of the control panel, in addition to the old control panel 106, a plurality of components controlled by the control panel 106 (particularly, components that cannot understand the signals output by the new control panel 400) are replaced. Thus, in the conventional replacement work of replacing the old control panel 106 and the plurality of components, the elevator cannot be operated until all of the old control panel 106 and the plurality of components are replaced, resulting in a long construction period and a long period during which the elevator cannot be used, causing inconvenience to the elevator users. Also, since there are many components to be replaced and the construction period becomes long, there is a problem that the burden on the workers for the replacement work is large.

[0078] ​​​​​​​​​​​​​​In the replacement work of this embodiment, if there is a component that cannot understand the signal output by the new control panel 400, in addition to the new control panel 400, a signal conversion device is installed. The signal conversion device converts the signal output by the new control panel 400 into a signal that can be understood by a plurality of components that were controlled by the old control panel 106, and outputs it to the plurality of components. Also, the signal conversion device converts the signal output by a plurality of components that were controlled by the old control panel 106 into a signal that can be understood by the new control panel 400, and outputs it to the new control panel 400. (Functional Configuration of Signal Conversion Device) Next, the functional configuration of the signal conversion device will be described. FIG. 5 is a block diagram showing the functional

[0079] configuration of the signal conversion device. In FIG. 5, each function of the signal conversion device 500 is realized by an input unit 501 on the component side, an input unit 502 on the new control panel 400 side, a signal conversion unit 503, an output unit 504 on the new control panel 400 side, and an output unit 505 on the component side. The input unit 501 on the component side receives the input of the upward signal output by each component of the elevator 100 to the control panel 106. The input unit 501 on the component side can be realized by, for example, a plurality of input terminals 401 (connection terminals) provided for each component. The input unit 502 on the new control panel 400 side receives the input of the downward signal output by the new control panel 400 to each component of the elevator 100. The input unit 502 on the new control panel 400 side can be realized by, for example, an input terminal 403 (connection terminal) provided corresponding to the new control panel 400.

[0080] The signal conversion unit 503 converts the upward signal received by the input unit 501 on the component side into the above-mentioned upward signal. The input unit 501 on the component side can be realized by, for example, a plurality of input terminals 401 (connection terminals) provided for each component. The input unit 502 on the new control panel 400 side receives the input of the downward signal output by the new control panel 400 to each component of the elevator 100. The input unit 502 on the new control panel 400 side can be realized by, for example, an input terminal 403 (connection terminal) provided corresponding to the new control panel 400. The input unit 502 on the new control panel 400 side can be realized by, for example, an input terminal 403 (connection terminal) provided corresponding to the new control panel 400.

[0081] The signal conversion unit 503 converts the upward signal received by the input unit 501 on the component side into the above-mentioned upward Convert it into another signal that has the same meaning as the up signal and can be understood by the new control panel 400. Also, the signal conversion unit 503 converts the down signal received by the input unit 502 on the new control panel 400 side into another signal that has the same meaning as the down signal and can be understood by each component that is the output destination of the down signal

[0082] Specifically, the signal conversion unit 503 can be realized by, for example, a processor constituted by a memory storing a signal conversion program, a CPU that executes the program stored in the memory, etc. Alternatively, the signal conversion unit 503 can realize its function by, for example, an FPGA (Field-Programmable Gate Array), an ASIC (Application Specific Integrated Circuit) dedicated for signal conversion, etc. The output unit 504 on the new control panel 400 side outputs the up signal converted into another signal that can be understood by the new control panel 400 by the signal conversion unit 503 to the new control panel 400. The output unit 504 on the new control panel 400 side can be realized by an output terminal 404 (connection terminal) provided corresponding to the new control panel 400. The output unit 505 on the component side outputs the down signal converted into another signal that can be understood by each component by the signal conversion unit 503 to the corresponding components. The output unit 505 on the component side can be realized by a plurality of output terminals 404 (connection terminals) provided for each component.

[0083]

[0084] Each part 501 - 505 included in the signal conversion device 500 is connected to the control panel 106 and the new control panel 400 ​​​​​​​​​​​​Similarly, it is housed inside an iron casing forming a box shape (see Fig. 8D). The signal conversion device 50 The casing of 0 is separate from the casings of the control panel 106 and the new control panel 400. The signal conversion device On the lower side of the casing of 500, an opening (the lower surface opening of the signal conversion device 500) is provided for routing the cables connected to the respective components of the elevator 100 inside the casing Note that each part included in the signal conversion device 500 may be housed inside the casing of the new control panel 400 That is, the signal conversion device 500 and the new control panel 400 may share the casing

[0085] The new control panel 400 that controls the elevator 100 using new technology has the same configuration as the old control panel 106. However, compared with the old control panel 106, in addition to higher performance, the size of the casing (i.e., the external dimensions of the new control panel 400) may be reduced When replacing such a new control panel 400 with the control panel 106, the size of the new control panel 400 (its casing) becomes smaller than the size of the old control panel 10 6 (its casing) 0.

[0086] When the old control panel 106 is installed in the machine room, the cables connected to the respective components of the elevator 100 are routed to the cable pit provided on the floor of the machine room and connected to the old control panel 10 6. The cable pit has a groove shape recessed from the floor surface of the machine room and is covered with a lid (see Figs. 8A to 8D).

[0087] The cables routed to the cable pit are pulled out onto the floor through the floor opening (see Fig. 8B) provided at the end of the cable pit on the side of the old control panel 106 and connected to the old control panel 10 6. Below the floor opening, it is recessed in a square shape from the floor surface. The cable pit and the floor opening are (see Fig. 8B). ​​​​, for example, a groove forming a cable pit and a square shape forming a floor opening are formed by pouring concrete on the floor of the machine room. It is formed by pouring concrete on the floor of the machine room.

[0088] The floor opening is rectangular or square on the floor with the side length dimension of one side being larger than the width dimension of the cable pit. Generally, the side length dimension of the floor opening is formed according to the size of the lower end of the housing of the old control panel 106. For this reason, when replacing the control panel 106 with a new control panel 400 smaller in size than the old control panel 106, if the new control panel 400 is simply installed on the floor opening, a part of the floor opening will remain open. With such an inadvertent opening on the floor, a part of the cable will be exposed, which is not preferable in terms of safety. Also, the working platform for the operator performing maintenance on the control panel and the like will be deteriorated, and there is a risk that the operator or the like may step off or trip when passing by, which is not preferable. When there is such an inadvertent opening on the floor, a part of the cable will be exposed, which is not preferable in terms of safety. Also, the working platform for the operator performing maintenance on the control panel and the like will be deteriorated, and there is a risk that the operator or the like may step off or trip when passing by, which is not preferable. When there is such an inadvertent opening on the floor, a part of the cable will be exposed, which is not preferable in terms of safety.

[0089] In the case of replacing a conventional control panel, in such a case, a part of the floor opening and the cable pit provided according to the size of the old control panel 106 is filled back with concrete or the like according to the size of the new control panel 400. When filling back, the laid cable is removed, the concrete is filled back, and the cable must be laid again after the concrete is completely cured. This increases the burden on the operator and lengthens the period during which the elevator 100 cannot be used, causing inconvenience to the users of the elevator 100. When filling back, the laid cable is removed, the concrete is filled back, and the cable must be laid again after the concrete is completely cured. This increases the burden on the operator and lengthens the period during which the elevator 100 cannot be used, causing inconvenience to the users of the elevator 100. This increases the burden on the operator and lengthens the period during which the elevator 100 cannot be used, causing inconvenience to the users of the elevator 100. This increases the burden on the operator and lengthens the period during which the elevator 100 cannot be used, causing inconvenience to the users of the elevator 100.

[0090] On the contrary, according to the replacement work method of this embodiment, by using a base mount The need for a recovery operation can be eliminated. Below, the base mount of the embodiment according to the present invention will be described. - The base mount will be described.

[0091] (An example of the structure of the base mount) Next, the structure of the base mount of the embodiment according to the present invention will be described. FIG. 6 is an explanatory diagram showing an example of the structure of the base mount. As shown in FIG. 6, the base mount 600 includes a support plate 601, a new control panel opening 602, legs 603, a through hole 604 for a control panel fixing bolt, a conversion device opening 605, a through hole 606 for a conversion device fixing bolt, and a through hole 607 for a base mount fixing bolt.

[0092] The support plate 601 has a substantially rectangular plate shape. The outer edge shape of the support plate 601 is larger than the floor opening. The support plate 601 can be realized by, for example, a steel plate. The new control panel opening 602 penetrates the support plate 601 in the plate thickness direction and opens smaller than the lower surface opening of the new control panel 400. The new control panel opening 602 can be formed by, for example, punching the steel plate that realizes the support plate 601. The legs 603 are provided on one surface side of the support plate 601. The legs 603 are positioned closer to the floor side than the support plate 601 when the base mount 600 is installed on the floor, and the lower end of the new control panel 400 is separated from the floor opening (the height of the floor) by a predetermined distance. Specifically, the legs 603 are formed by, for example, shaping a steel plate into a square tube shape and fixing one wall surface of the square tube to one surface side of the support plate 601 by welding or the like.

[0093]

In step S70 5, as shown in FIG. 8D, install the signal conversion device 500 on the base mount 600 such that the lower surface opening of the signal conversion device 500 faces the opening 605 for the conversion device. In step S705, install the signal conversion device 500 on the base mount 600 such that the pre-provided bolt holes for fixing (not shown) in the signal conversion device 500 and the through holes 606 for the fixing bolts of the conversion device provided in the base mount 600 face each other along the vertical direction.

Thereby, the signal conversion device 500 can be fixed to the base mount 600. The processing of step S704 and the processing of step S705 may be in the reverse order of execution. That is, after installing the signal conversion device 500 on the base mount 600 installed on the floor surface 801, the new control panel 400 may be installed. Also, if the installation of the signal conversion device 500 is not required, the processing of step S705 may be omitted. If the installation of the signal conversion device 500 is not required, the opening 605 for the conversion device is made into the opening 6 for the conversion device. In step S705, install the signal conversion device 500 on the base mount 600 such that the pre-provided bolt holes for fixing in the signal conversion device 500 and the through holes 606 for the fixing bolts of the conversion device provided in the base mount 600 face each other along the vertical direction.

[0108] In step S705, install the signal conversion device 500 on the base mount 600 such that the pre-provided bolt holes for fixing in the signal conversion device 500 and the through holes 606 for the fixing bolts of the conversion device provided in the base mount 600 face each other along the vertical direction. In step S705, insert a conversion device fixing bolt (not shown) into the pre-provided bolt holes for fixing in the signal conversion device 500 and the through holes 606 for the fixing bolts of the conversion device, and tighten the conversion device fixing bolt and the nut so as to sandwich the housing 807 of the signal conversion device 500 and the base mount 600. Thereby, the signal conversion device 500 can be fixed to the base mount 600. In step S705, insert a conversion device fixing bolt (not shown) into the pre-provided bolt holes for fixing in the signal conversion device 500 and the through holes 606 for the fixing bolts of the conversion device, and tighten the conversion device fixing bolt and the nut so as to sandwich the housing 807 of the signal conversion device 500 and the base mount 600. Thereby, the signal conversion device 500 can be fixed to the base mount 600. In step S705, insert a conversion device fixing bolt (not shown) into the pre-provided bolt holes for fixing in the signal conversion device 500 and the through holes 606 for the fixing bolts of the conversion device, and tighten the conversion device fixing bolt and the nut so as to sandwich the housing 807 of the signal conversion device 500 and the base mount 600. Thereby, the signal conversion device 500 can be fixed to the base mount 600. In step S705, insert a conversion device fixing bolt (not shown) into the pre-provided bolt holes for fixing in the signal conversion device 500 and the through holes 606 for the fixing bolts of the conversion device, and tighten the conversion device fixing bolt and the nut so as to sandwich the housing 807 of the signal conversion device 500 and the base mount 600. Thereby, the signal conversion device 500 can be fixed to the base mount 600. In step S705, insert a conversion device fixing bolt (not shown) into the pre-provided bolt holes for fixing in the signal conversion device 500 and the through holes 606 for the fixing bolts of the conversion device, and tighten the conversion device fixing bolt and the nut so as to sandwich the housing 807 of the signal conversion device 500 and the base mount 600. Thereby, the signal conversion device 500 can be fixed to the base mount 600.

[0109] The processing of step S704 and the processing of step S705 may be in the reverse order of execution. That is, after installing the signal conversion device 500 on the base mount 600 installed on the floor surface 801, the new control panel 400 may be installed. Also, if the installation of the signal conversion device 500 is not required, the processing of step S705 may be omitted. That is, after installing the signal conversion device 500 on the base mount 600 installed on the floor surface 801, the new control panel 400 may be installed. That is, after installing the signal conversion device 500 on the base mount 600 installed on the floor surface 801, the new control panel 400 may be installed. Also, if the installation of the signal conversion device 500 is not required, the processing of step S705 may be omitted.

[0110] If the installation of the signal conversion device 500 is not required, the opening 605 for the conversion device is made into the opening 6 for the conversion device. It may be closed by covering it with a steel plate or the like larger than 05. In this case, the opening for the conversion device In the steel plate that closes the 605, at a position overlapping with the through-hole 606 for the conversion device fixing bolt, a bolt for fixing the steel plate that closes the opening 605 for the conversion device to the base mount 600 is inserted. A through-hole may be provided. For fixing the steel plate that closes the opening 605 for the conversion device The through-hole provided may be less than the number of through-holes 606 for the conversion device fixing bolts. Since the steel plate that closes the opening 605 for the conversion device is lighter than the signal conversion device 500, By making the number of through-holes for inserting the bolts less than the number of through-holes 606 for the conversion device fixing bolts, the steel plate can be securely fixed and the burden on the operator for fixing the steel plate can be reduced. This can be achieved.

[0111] Next, the cable 804 is connected (step S706). In step S706 Of the cables 804 routed from each component of the elevator to the floor opening 803, the cable 804 to be connected to the new control panel 400 is pulled out above the base mount 600 through the new control panel opening 602 and connected to the new control panel 400. Specifically, the cable 804 connected to the new control panel 4 00 is connected to the input terminal 403 and output terminal 404 of the new control panel 400.

[0112] Also, in step S706, of the cables 804 routed from each component of the elevator to the floor opening 803, the cable 804 to be connected to the signal conversion device 500 is pulled out above the base mount 600 through the conversion device opening 605 and connected to the signal conversion device 500. Specifically, the cable 804 connected to the signal conversion device 500 is the signal ​​​​​​​​It is connected to the input unit 501 on the component side and the output unit 505 on the component side in the conversion device 500 .

[0113] The base mount 600 has a floor opening 803 (at the height of the floor 801) and A space is provided between the support plate 601 and the new control panel 400. 500 and above the floor opening 803, A space is provided in height. Also, a space is provided between the legs 603. Therefore, the worker can insert the container into the floor opening 803 through the space secured below the support plate 601. It is easy to insert your hand into the cable 804 and then connect the cable 804 to the new control panel 400 or the signal The new control panel 400 and the housing 806 of the signal conversion device 500 are connected through the bottom opening of the conversion device 500. This allows the installation of new control panel 400 In addition, compared to a case where the lower end of the signal conversion device 500 is directly fixed to the floor surface 801, This allows the work of connecting the cable 804 to be done easily and quickly, reducing the burden on the worker. It is possible.

[0114] In step S706, the signal conversion device 500 and the new control board 400 are Specifically, for example, the input of the new control panel 400 is connected to the cable 804 for transmitting and receiving signals. The output terminal is connected to the output section 504 on the new control panel 400 side. , the output terminal 404 of the new control board 400 is connected to the input section 502 on the new control board 400 side.

[0115] After that, the operation is checked (step S707) to see if the elevator 100 is operating normally. In step S707, for example, Based on the upstream signals input from each component to the new control panel 400 via the signal conversion device 500 , the operation of the new control panel 400 is checked. Specifically, for example, the operation panel 101 of the car 101 b is operated, and it is checked whether the car 101 moves up and down to the specified floor .

[0116] Also, in step S707, for example, the operations of each component according to the downstream signals input from the new control panel 400 via the signal conversion device 50 0 are checked. Specifically, for example, the operation panel 111 provided at the landing 110 is operated, and a call is generated for the corresponding floor according to the operation, and it is checked whether the car 101 moves to the floor .

[0117] In step S708, based on the confirmation result in step S707, based on the upstream signals input from each component to the new control panel 400 via the signal conversion device 500, it is determined whether the new control panel 400 operates or all components operate, and also based on the results such as whether they operate according to the downstream signals input from the new control panel 400 via the signal conversion device 500, it is determined whether the elevator 100 operates normally .

[0118] According to the specifications of the new control panel 400, by connecting the signal conversion device 50 0 between each component and the new control panel 400, even when replacing the control panel 106 with the new control panel 400, the new control panel 400 can understand the signals output by the components . Also, according to the specifications of the new control panel 400, by connecting the signal conversion device 500 between each component and the new control panel 400, even when replacing the control panel 106 with the new control panel 400, the components can understand the signals output by the new control panel 400 and operate accurately . ​​​​

[0119] Thus, according to the specifications of the new control panel 400, by connecting the signal conversion device 500 between each component and the new control panel 400, even if a part of the component to be replaced is a component that the new control panel 400 cannot directly control, such as a component made by another manufacturer or a component with different specifications, the replacement of the control panel can be performed without replacing the said component. This makes it possible to replace the control panel without replacing all the components, thus reducing the burden on the operator and shortening the working time, and also suppressing the cost of a single construction project.

[0120] In step S708, when the elevator 100 operates normally (step S7 08: Yes), the replacement work of the control panel 106 is terminated. On the other hand, in step S708 when the elevator 100 does not operate normally (step S708: No), connection confirmation is performed (step S709), and the process proceeds to step S707 to perform the operation confirmation again. In step S709, for example, the connection state between the component that did not operate according to the signal output from the new control panel 400 and the new control panel 400 is confirmed, or the connection state is adjusted.

[0121] The processes of step S707, step S708, and step S709 are repeated for the new control panel 400, the signal conversion device 500, and each corresponding component until it is confirmed that they operate normally. This ensures the safety of the elevator users.

[0122] ​​​​​​The maintenance management of the elevator 100 is realized, for example, by periodically checking the operation history of the elevator 100 to be maintained based on the communication results with the terminal for inspection with the control panel 106 of the elevator 100, or by performing component replacement based on the confirmed operation history. Also, the maintenance management of the elevator 100 is realized, for example, by periodically communicating between the control panel 106 and the management server computer, executing a diagnostic operation, and performing component replacement according to the result of the diagnostic operation. In such maintenance management of the elevator 100, conventionally, for example, in an elevator 100 in which each component is controlled by a dedicated ASIC, when a part of the components is to be replaced with new components, it is assumed that the new components cannot be controlled by the existing ASIC. In such a situation, the new components are limited to those that can be controlled by the existing ASIC. More specifically, for example, when the hoist 104 controlled by a dedicated ASIC is to be replaced, even if there is another hoist 104 with lower power consumption and higher output than the existing hoist 104, it cannot be replaced with the other hoist 104 due to the limitation of the existing ASIC. Therefore, the person in charge of managing the elevator 100 etc. has no choice but to select either to replace it with a hoist 104 that can be controlled by the existing ASIC or to perform a renewal including the existing ASIC, and there has been a situation where the degree of freedom of maintenance management by the person in charge of managing the elevator 100 etc. is low. Also, the communication between the control panel 106 related to the maintenance management of the elevator 100 and the inspection terminal

[0123] In the maintenance management of the elevator 100 like this, conventionally, for example, in an elevator 100 where each component is controlled by a dedicated ASIC, when some components are to be replaced with new components, it is assumed that the new components cannot be controlled by the existing ASIC. In such a situation, the new components are limited to those that can be controlled by the existing ASIC. More specifically, for example, when the hoist 104 controlled by a dedicated ASIC is to be replaced, even if there is another hoist 104 with lower power consumption and higher output than the existing hoist 104, it cannot be replaced with the other hoist 104 due to the limitation of the existing ASIC. Therefore, the person in charge of managing the elevator 100 etc. has no choice but to select either to replace it with a hoist 104 that can be controlled by the existing ASIC or to perform a renewal including the existing ASIC, and there has been a situation where the degree of freedom of maintenance management by the person in charge of managing the elevator 100 etc. is low.

[0124] In the maintenance management of the elevator 100 like this, conventionally, for example, in an elevator 100 where each component is controlled by a dedicated ASIC, when some components are to be replaced with new components, it is assumed that the new components cannot be controlled by the existing ASIC. In such a situation, the new components are limited to those that can be controlled by the existing ASIC. More specifically, for example, when the hoist 104 controlled by a dedicated ASIC is to be replaced, even if there is another hoist 104 with lower power consumption and higher output than the existing hoist 104, it cannot be replaced with the other hoist 104 due to the limitation of the existing ASIC. Therefore, the person in charge of managing the elevator 100 etc. has no choice but to select either to replace it with a hoist 104 that can be controlled by the existing ASIC or to perform a renewal including the existing ASIC, and there has been a situation where the degree of freedom of maintenance management by the person in charge of managing the elevator 100 etc. is low.

[0125] Also, the communication between the control panel 106 related to the maintenance management of the elevator 100 and the inspection terminal Alternatively, communication between the control panel 106 and the management server computer often uses signals specific to each elevator manufacturer, resulting in the current situation. For this reason, it has been difficult for independent elevator maintenance service companies, independent of the manufacturer or elevator management companies partnered with the manufacturer (hereinafter referred to as "manufacturer, etc." as appropriate), to perform maintenance management on the independent elevator 100.

[0126] In the current situation where communication using signals specific to each manufacturer is carried out during elevator 100 maintenance management, new components replacing existing components (old components) must be selected within the range specified by the manufacturer, etc. for each elevator 100, resulting in a situation where the freedom of maintenance management by the elevator 100 management responsible person, etc. is low.

[0127] In addition, in the current situation where communication using signals specific to each manufacturer is carried out, manufacturers, etc. for each elevator 100 can easily uniquely set the cost required for elevator 100 maintenance management ( maintenance management cost), making it difficult for elevator 100 management responsible persons, etc. to reduce the maintenance management cost they bear.

[0128] The safety and sense of security of elevator 100 users tend to increase as the frequency of elevator 100 maintenance inspections increases. On the other hand, in the above situation, in order to reduce the maintenance management cost, if the frequency of maintenance inspections is suppressed to the minimum stipulated by the guidelines of the Ministry of Land, Infrastructure, Transport and Tourism or a frequency close to it, it becomes difficult to achieve both the reduction of the maintenance management cost and the improvement of the safety of elevator 100 users.

[0129] On the other hand, according to the method for replacing the control panel in this embodiment, as described above, by connecting the signal conversion device 500 between the existing components and the new control panel 400, the elevator 100 can be operated even in a state where the existing components and the new components coexist. As a result, the replacement work from the existing components to the new components can be carried out dispersedly for each component. And thereby, a part of the components can operate the elevator 100 during each replacement work.

[0130] In the above-described embodiment, the elevator 100 that controls each component by executing various processes such as signal conversion processing using the CPU 401 provided in the new control panel 400 has been described. However, the control of the elevator 100 is not limited to being realized using the CPU 401. Instead of the CPU 401, for example, an ASIC which is an integrated circuit for a specific purpose integrating a plurality of circuits, or an FPGA which is an integrated circuit whose configuration can be arbitrarily set after manufacturing may be used to realize the control of the elevator 100.

[0131] In the above-described embodiment, the rope-type elevator 100 has been described. However, the elevator 100 according to this invention is not limited to the rope-type elevator 100. Instead of the rope-type elevator 100, or in addition to the rope-type elevator 100, for example, a hydraulic elevator 100 may be used.

[0132] Also, in the above-described embodiment, the method for replacement work when replacing the old control panel 106 having a communication function with the new control panel 400 has been described. However, the old control panel 106 has a communication function. ​​​​​​​​​​​​​ is not limited to the obtained ones. For example, for reasons such as not assuming remote monitoring during installation the old control panel 106 that does not have a communication function and has a separate communication device connected after installation is replaced with a new control panel 400, the control panel replacement construction method according to the present invention can also be applied. In this case, for example, the old control panel 106 and the communication device are replaced with the new control panel 40 0.

[0133] As described above, the control panel replacement construction method of the embodiment according to the present invention is a control panel replacement construction method for controlling a plurality of components provided in the elevator 100, and removes the old control panel 106 installed on the floor surface 80 1, opens the floor surface opening 803 that guides the cable 804 laid below the floor surface 801 and connects the old control panel 106 to a plurality of components to the old control panel 106, and has an outer edge shape larger than the floor surface opening 803. A base mount 60 1 having a plate shape and a new control panel opening 602 that penetrates the support plate 601 in the plate thickness direction and is smaller than the lower surface opening of the new control panel 400 is installed on the floor surface 801 with the support plate 601 facing the floor surface opening 803, installs the new control panel 400 on the new control panel opening 602 of the base mount 60 0 installed on the floor surface 801, and routes and connects the cable 804 from the floor surface opening 803 through the new control panel opening 602 to the new control panel 400. This is characterized by

[0134] According to the control panel replacement construction method of the embodiment according to the present invention, the cable 804 laid from a plurality of components to the floor surface opening 803 can be used to connect the new control panel 400 and a plurality of components. Thereby, during the control panel replacement work, in the conventional replacement work ​ It is possible to eliminate the laying work of a new cable 804 which was essential, and to replace the control panel It is possible to reduce the burden on the workers involved in the construction work and shorten the working hours.

[0135] Also, according to the control panel replacement construction method of the embodiment according to the present invention, a support plate 601 having a new control panel opening 602 that opens smaller than the lower surface opening of the new control panel 400 is provided at a position facing the floor opening 8 03. By installing the base mount 600, regardless of the size of the floor opening 803 provided according to the size of the old control panel 106, the support plate 601 and the new control It is possible to reliably cover the upper part of the floor opening 803 with the panel 400. With the progress of technology in recent years, in addition to the high performance of the control panel, the miniaturization of the control panel has been progressing, If the new control panel 400 is simply installed on the floor opening 803 provided according to the size of the housing of the old control panel 106, a part of the floor opening 803 will remain open.

[0136] In this case, the vicinity of the new control panel 400 will be in a partially recessed state and a part of the cable 804 will be exposed, so there is a risk of damaging the cable 804, the work platform for the workers performing maintenance of the control panel etc. will deteriorate, and there is also a risk that the workers etc. may step on or trip over their feet when passing by, which is not preferable.
